Example:
① 
100 = 0.27 l/s
② ∆Pv100 = 9 kPa
③ kvs value required = 3.5 m3/h
∆Pv100 | = | Differential pressure across the fully open valve and the valve's control path A → AB (2-port valves), AB → A (3-port diverting valves) by a volume flow |
| = | Volume flow through the fully open valve (H100) |
∆Pmax | = | Max. permissible differential pressure across the valve's control path, valid for the entire actuating range of the motorized valve |
100 kPa | = | 1 bar ≈ 10 mWC |
1 m3/h | = | 0.278 l/s water at 20 °C |
